Seattle Seahawks cornerback Richard Sherman arrived at a press conference on Wednesday decked out in his wizarding finest.

Sherman entered the press conference playing the Harry Potter theme song on his phone and wielding what appeared to be a replica of Albus Dumbledore’s wand while wearing a full Gryffindor robe. But the 28-year-old didn’t just wear the costume — he took questions as a wizard.

“When you’re a wizard like we are out here, sometimes you have to show it to the Muggles out in the world,” Sherman said when asked about his unusual getup, according to Seahawks.com, and added that some of his teammates have alter-egos, too. “We’ve got a lot of wizards — my son’s a wizard, Earl Thomas does some magical things, Michael Bennett is Black Santa but he’s also a wizard — so you know, you just have a good time.”

Earlier on in the press conference, Sherman explained that he was revealing his inner wizard at the request of his 1-year-old son, Rayden.

That said, the Compton, California, native was likely equally excited about the costume as his son. A 2014 New York Times profile revealed the Stanford grad was a Harry Potter superfan who devoured the books and made it to the midnight debuts of each film (although not in costume, sadly).

That certainly explains why he’s so well-versed in the rules of Quidditch. In the conference, Sherman explained that playing five quarters of football (which he and the rest of the Seahawks did Sunday night in an overtime game against the Arizona Cardinals that ended in a tie) was just marginally tougher than playing in a Quidditch match.

“Five quarters of football is pretty tough, but Quidditch — the beaters, the chasers, trying to find the golden snitch, things like that — that’s tough,” he said. “Five quarters of football, though, in the elements, I’d say that’d take the cake.”

Another reporter asked Sherman how long it took for him to “feel human again” after Sunday’s grueling game.

“Well, I’m definitely a wizard, so if you’re asking if I feel like a Muggle again, I don’t,” he responded. “But I started feeling better probably around late yesterday, last night, just getting more fluids in me and more energy, legs started getting back under me.”

He added that he was looking forward to flying under the radar when he goes out in costume with his son on Halloween night.

“He’s going to have a mask on, I’m going to have this on, nobody’s going to have any idea,” Sherman said as he reached by his side for a pair of round Harry Potter-style wire glasses. “This is all you’ve got to do. Clark Kent did it. You’ve just got to put the glasses on. Bam, no longer Richard Sherman. Can’t even tell anymore, right?”
